The app here I used is Gparted , installing it with a single command and within minutes adding(mounting) it to my list of partitions. check video if you really want to see how does it operate. really handy tool.
NOTE:- at end what you dont see in video is I added following single line to a file called fstab so everytime i reboot, this NEW partition also loads without my needing to do command things again and again.

[anshu@Fedora7 ~]$ sudo vi /etc/fstab
/dev/sda4 /Opvms ext3 defaults 0 0

Screenshot below is how it looks in end.
